The deity of Christ is a key part of the foundation upon which Christianity is built. If Christ were only a man and not the God-man He could not have died to save the lost. The Scripture claims that Christ is the exact image or representation of deity (Heb. 1:3). Christ claimed to be God Himself (Jn. 5:18; 10:30). As God He thus possesses all the attributes of deity. He is eternal (Mic. 5:2; Jn. 1:15, 8:58), omnipotent (Matt. 28:18; Heb. 1:3), omniscient (Jn. 16:30; Col. 2:3), and omnipresent (Matt. 18:20; Jn. 3:13). Christ is the Creator and Sustainer (Jn. 1:3; Col. 1:16-17) of the universe. He has risen from the dead (Mk. 16:9), forgives sin (Matt. 9:2; Jn. 7:48), and thus needs to be worshipped (Matt 28:9). In Him dwells the fullness or totality of the essence of God (Jn. 1:1; 20:28; Col. 2:9). Everything that God is, Christ is (Ti. 2:13).
In order for Christ to be the payment for the sins of man (Heb. 5:9), He not only had to be 100% Deity, but 100% humanity. (This is a major point that the Jehovah’s Witnesses and Mormons miss). Christ took on His human nature when He was conceived and born (Matt. 1:18-25; Lk. 1:26-35, 2:5-7; Gal. 4:4). He grew (Lk. 2:52) and had flesh, bones and blood (Lk. 24:39; Heb. 2:14). Because He was fully man, Christ experienced feelings common to man such as hunger, sleep and thirst (Matt. 4:2; 8:24; Jn. 4:7). Christ also affirmed that just as He was God, He was also man (Jn. 8:40).
The coming together of Christ’s two natures into one person is known as the Hypostatic Union. Christ did not give up Deity (Rom. 1:1-4; Phlp. 2:6-7), nor did He change His Deity in the taking on of flesh (Jn. 1:1-2, 14). Christ was and is 100% deity, while becoming 100% flesh. The two natures of Christ have never mixed; they are distinct, and will remain as such in Christ the God-man forever (Jn. 20:19-20; 1 Tim. 3:6). Without Christ taking on flesh, He could never have tasted death for mankind and become the captain of our salvation (Heb. 2:9-10).
